title: [Characteristic of the hepatic tissue degradation processes underlying the development of its local and distant lesions].
abstract: The processes associated with liver disruption caused by a blunt abdominal injury have been investigated on a model of continuous media deformation. It was shown that local primary injuries to the liver result from stress-induced tissue stretching, compression, and shear in the longitudinal direction. They have a layered relief due to transverse fissures. The peripheral ruptures result from tissue extension under effect of overall liver deformation. They are not deep and have a uniform relief created by alternating low tubercles and superficial fissures oriented at the right angle to the surface. Antishock ruptures are the consequences of tissue extension or stretching/compression during local and overall deformation of the liver surface. They develop in the longitudinal direction, have a non-uniform relief created by alternating high prominences and numerous fissures differing in both the depth and the extension and oriented at the right angle to the liver surface. Central ruptures result from tissue stretching accompanying overall deformation of the organ. They are directed perpendicular to the direction of the surface force, have the longitudinal direction and non-uniform relief.
